Title:
RESONANCE-TYPE NON-CONTACT POWER SUPPLY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/172899
Kind Code:
A1
Abstract:
A resonance-type non-contact power supply system is configured such that a power supply unit can alter the output frequency, and has an impedance measurement means (impedance measurement unit) that measures the input impedance of a resonance system. The system also has a control means that performs control such that official power supply to power receiving equipment occurs after the output frequency (fo) of the power supply unit is changed so as to be within a range among ranges of frequency f1≤fo≤ frequency f2, frequency f3≤fo≤ frequency f4,⋅⋅⋅, frequency f2n-1≤fo≤f2n. Frequencies f1, f2, f3, f4⋅⋅⋅, f2n-1, f2n (f1
